Hello @Popeye ,
The electronic speed control (ESC) feature allows to control the motor speed with a PWM signal in input, for example on the B-G431B-ESC1 boards it is possible to use this feature to control the motors of a drone sending a PWM signal with a different duty cycle to switch the motor to armed, armed with a minimum speed, armed with a maximum speed and unarmed state.
You can find more details on this example on this link : click here
on the chapter "Connection and first execution of the electronic speed controller (ESC) program".
